Off to a good start mate! I’m currently doing a regionnaire challenge with South Shields in the North East, it’s a challenging but fun way of playing. Hopefully you’ll have more choice of players than I do coming out of London!
With regards to the player search filters, the below links to MaddFm’s blog where he shares player search filters for each of the regions, I downloaded the one for the North East and is working well.
